Zea/Z Patented July 7, 1936 STATES PATENT QFFICE 1 Claim.

My invention relates to a device for exercising the abdominal muscles of the human body, and it consists in the constructions, arrangements and combinations herein described and claimed.

It has become a well accepted fact that in order to reduce the waistline of the human body, the body should be bent at the waistline repeatedly. The most common of the exercises followed is for the person to lie flat on his back and alternately raise and lower his back from the supporting surface, but in order to obtain the most beneficial results, the legs of the body should be maintained substantially fiat upon the surface.

It is therefore an object of the invention to provide an appliance which may be readily anchored and applied to the lower limbs of the person for the purpose of maintaining the limbs substantially fiat upon the supporting surface.

It is also an object of the invention to provide a device which is readily adjustable to accomodate persons of different stature, as well as permitting pcsitioning of the device at various points along the thigh portions of the legs, as desired.

It is a still further object of the invention to provide a device which is of extreme simplicity both in manufacture and in use, and which may be quickly dismanted for storage in the baggage of the person when travelling.

Additional objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawing, wherein Figure 1 is a side elevation of a person in one position during an exercise, showing my device installed.

Figure 2 is an enlarged front View of the device, the covering of one of the hook members being partially broken awa Figure 3 is a detail view illustrating the anchorage and adjusting means.

In carrying out the invention I make use of a rod l0, preferably of metal, bent intermediate its ends to provide a loop II, the portions of the rod erably I employ a rubber tubing which may be slipped over the ends of the rod and adjusted to final position and secured by cementing, or otherh sired length although in practice it has been found that six to eight inches of chain is ample, to one end of which there is attached a snaphook is. The hook is is engageable with a screw-eye 29, by means of which the chain may be fixed to the floor or other supporting surface.

In use, the screw-eye 26 is anchored to the floor with the snap-hook l S engaged therein, and the person seats himself upon the floor or other surface with his legs disposed upon opposite sides of the eyelet 29, as shown in Figure 2. The l 6 is then laid upon the legs, above the knees, and a link of the chain then adjusted to the hook l1. This adjustment is preferably such that the limbengaging hooks I2 rest comfortably upon the legs and undue slackness of the chain is avoided. The

person now proceeds with his exercise which consists of alternately raising and lowering his back from prone to upright sitting position, stretching his arms and body forwardly as far as possible, such as in an attempt to touch his toes. will be obvious that the person may partake of movements laterally from side to side, and in all such movements the legs will be maintained substantially flush with the supporting surface, and

the muscles in the region of the waistline exercised to produce beneficial results.

While I have shown and described a preferred construction, it will be apparent that changes may be made, and I therefore consider as my own all such modifications as fairly fall within the scope of the appended claim.

I claim:

A device for exercising the muscles of the Waistline comprising a yoke-like member for engaging the legs of a person above the knees, said yoke ineluding a loop portion therebetween, a clip member mounted in the bight of the loop, a hook member on the clip member, and a chain having one end attached to a screw-eye for securement to a supporting surface, the opposite end of the chain connected to said clip, the intermediate portions having adjustable attachment with the hook.

WILLIAM PETCOFF.
